The SB2000 replaces the SB12 NSD, but the goods news is that our suppliers have a good deal of stock left. Roughly the same performance, but far, far less expensive.

We are selling them for R9900 inc each. At that price point, in terms of clean output and deep bass extension, I don't think there is anything that can touch this level of performance. A full performance analysis can be found here

For comparative purposes, in terms of deep bass extension down low (~ 20 Hz), a single SB12 NSD is roughly twice as powerful as a Velodyne EQ Max 15 (6 dB+ differential). Not bad for a subwoofer that is roughly half the price.

Judging by the happy customers all over the web for pure stereo listening, I think they've made a gem here. Sealed design, so no potential port chuffing either.
